So I got 4 units 2 of each mikeywith helped me acquire them. M30s first As you can see they are very close equal. I checked off the two that are the m30s 95 or 96 th and set to 3200 watts. one pulls 3214 watts and does 96 and change the other one pulls 3171 watts and does 95 and change both do 33 watts and change

space note this machine has an error. It is my 3 phase leg a sometimes drops low. so if you are wired a/b or a/c you go to about 200 volts. and get this 206 error. we are in Clifton NJ and our power grid is nasdaq's back up it is tested 2 times a month and we drop down in volts.

This gear is stable and runs a lot like the m10 or the m20 or the m50.
I will get access to the m50 and post on it later.
comments are welcome.

Let us check your voltage at the PSU meter, go to whatsminer tool and follow this.
Settings > display mode > custom > add PowervIn
This will display the voltage at the PSU, yours seems to be below 200v which is why you get that error.
Also, you can add EnvTemp which is vrery useful too.

I have sensor push app. the room is 65 f in and 92 f out also we have only two of four exhaust fans turned on. I will check current volts. ev temp 25 and 26 c which is good. volts are 202 and 201 need to talk to power guy

Those can be somehow inaccurate since temps inside the farm will differ by a considerable margin depending on the airflow, turbulence, not enough exhaust causing heat to re-enter the miner, not enough intake space and etc. As you can see the miners are reporting 25-26c while your sensor is reporting 18.4, that's off by nearly 7 degrees, it's always best to check the miner's temp sensor rather than external sensors. But anyway, temps are still good, and don't worry much about them even if the room heats up, the miner will tune lower and will go into protection mode both on PSU and hashboard levels if temps can't be kept low enough. volts are 202 and 201 need to talk to power guy That is pretty low, in my previous post I meant to say below 220v, which is the minimum stated by the manufacturer, but I have tested some M30s all the way down to 205v and they ran just fine, even those that threw a voltage error did not seem to bother and just kept going. I am pretty interested in hearing the compassion part between the M30 and the M50 especially that now the price difference between the two is just about 2$ per th. A pro tip, going to the Whatsminer Tool and going to display settings, you will find a lot of fun stuff to show like the daily power consumption, also you could exclude a lot of the not-so-important info like the power supply version and all that things that you won't need for daily monitoring, just to keep 4-6 columns that you actually use.

I am going to check the other building with the m50s now. other building is 230 and 230.5 need to talk to electrical guy.

Seems to me that Whatsminer is good choice in value since they appear to be a bit more stingy with their reporting hashrate when compared to Bitmain.
To me that means the M50 units are tested properly and are sold knowing that they are solid at exceeding their performance specs.
I have 7 x M50's total in the stable and all of them exceed their expected hashrate from the manufacturer.
The majority of the units I have are the 108/110Th/s units and are all pushing over 111 poolside!
I have a single 112/114Th/s unit that's pushing 117Th/s...
And I have a single one of their 118/120Th/s units that is crushing 121-122Th...
Gearing up to roll out quite a few of the 118/120Th units shortly! :~)

230v is great, those m50 gears must be running without much effort, anything between 220v and 240v is good, higher is better for PSU, cables and everything else that carries power to the miner, slightly below 220v i would not bother, temprary below 210v is ok, but running steady for long period of time at 203v is something i won't reccomend, so ya sure thing call the electric guy, it is thier JOB to give you proper voltage input since you are paying for it. @Sledge0001, I have bought and sold hunderds of the m30s, +, ++, various m50 models were sold to my clients, none of them hashed at specs, all run higher which is great and people loved it except for one client who was mad at me because i sold him some 100th m30++ which did 106th and he said his pdu was near full and could not handle the extra 200w per miner lol, luckly he was able to use powerlimit and did not insist on returning , I now have to make everyone aware that I won't be responsible for gears that do slightly higher hashrate than what is on the label.

Yeah that room has over 40kwatts of gear in it. WE ARE Waiting for a new panel the panel is 80 years old. been a long wait. I will need to put some bitmain gear there and move the m30's to the other room. here is the m50 room it has over 100kwatts of gear.

Another pro tip, just mouse hover on the error when viewing the Whatsminer tools and it will tell you what the error means without having to fo to the miner webpage, also, double click on the miner's row takes you to the webpage of the miner. I would like to thank you for both using my services as well as making the review, I would have loved to see you run both gears at the same place so we can compare temps, fans and power, doing so when each model runs in a different place with different voltage and cooling will not be fair.

Hmmm, I guess I didn't know there are different M50 miners. Mine are M50s+ and average 130TH/s at 25J/TH = 3250W and are clearly averaging 130

Yours are the "S" model, the "S" after any Whatsminer model represents a more effienct and usually more hashrate gear than the non-S, and then they have the "+, the more of it the more efficient, so any S++ model is better than S and better than S+ and so on. tho are you sure yours has a +? That model is super rare, it has not been listed on their official distributes for months, which suggests that they made a very limited quantity of it, the currently available models are just the M50s and the M50, with efficiency ranging between 25w/th to 29w/th, and hashrate that goes from 108th to 130th +-5%. The difference in price, however, is very unreasonable IMO, for example, it's 6$ difference between the 28w and the 25w versions, not sure if that is worth it for a power rate that's below 10c per kWh.

They are what I said. As for price well it was back in Feb ... but anyway was 26.4 but included taxes, delivery, everything.

New image all four units in the asic room nice voltages but space is a bit hot. I know why and will need to shift some lighter duty gear .. IE: {M30s+} {L3+} {M30s+} {L3+} {M50} {L3+} {M50} will be the new shelf setup vs M30s+,M30s+,M50,M50,L3+,L3+,L3+

New image all four units in the asic room nice voltages but space is a bit hot. Actually, temps are not bad at all; fans are running at 5k rpm, which is not 100% since that is 7k rpm; the max temp for the hashboard is 80 c, which you are still 10 degrees away from; so unless the outside temperature increases by another 5-7 c, I do not see a problem. One thing to know about whatsminer vs. other miners is that the miner's case is designed to get rid of heat, think of it as a large heatsink. You will notice they are hot to touch from the outside, unlike most other gears, so they cannot be stacked too close to one another. I prefer to keep 5 cm of space between them to allow the chasis to get rid of the heat easier. Actually, judging by the Envtemp of the four miners, you can guess which two are located in the middle.

I was considering putting this between units. https://www.lowes.com/pd/Reflectix-2-in-x-30-ft-Reflective-Insulation-Tape/3012014https://www.lowes.com/pd/GreenGuard-1-X-2-X-2-Project-Panel-LG-1/5001929511 [m30s+] _|_ repeat. that would space the units say 3 inches and have a wall in-between the units. I know my cold side is very cold so if a bit of air moves between the units it should work. I think I can build three walls for 12 dollars

Both links are not working for me, I get this error. But I get the idea, I don't think it will do you any good, in fact, it could have a negative impact as those walls could trap the heat there and cause the miner to overheat, I'd say just make enough space between them, even better to space them with other low-power gears like your L3s, keep them clean and they will run just fine, I ran these monsters in 45c amp temp at my previous small farm which had terrible cooling, and they are still running, these are not the average Bitmain gears that would break easily. Not saying you should toast them, but I see nothing wrong with the current temps.
